Lesson Procedure

Time	Activity	Description
5 min	Opening / Review	Quick review: What is a line plot? Ask students to share examples from everyday life.
10 min	I Do	Teacher models reading a simple line plot using fractions (e.g., measuring rainfall in fractions of an inch). Demonstrate how to read marks and convert them into fractions with denominators 2, 4, 8.
15 min	We Do	Together with the class, analyze a new line plot showing lengths of pencils. Students call out measurements; teacher writes fractions and discusses denominators.
15 min	You Do (Pair-Share)	Students work in pairs to read another line plot showing data (e.g., number of pets owned) and write out the fractions shown. Pairs share responses aloud.
10 min	Small Group Differentiation	Group A (on-level): Practice with line plots and fractions with denominators 2,4,8. Group B (below level): Use line plots with denominators 2 and 4 only, use visual fraction strips. Group C (advanced): Challenge with denominators 5, 10, and 20 included.
5 min	Closure	Recap key points with a thumbs-up/thumbs-down check: Can you read a line plot? Can you write the fractions for the data? Preview tomorrow’s lesson on computations with these fractions.

10 min	I Do	Teacher models adding two fractions from a given line plot (e.g., lengths of two steps). Show visual fraction strips and number line to add fractions with unlike denominators (e.g. 1/4 + 1/3).
15 min	We Do	Class solves another addition problem from data: sum of times to complete activities on a line plot. Teacher guides to find common denominators and simplify. Students use mini whiteboards to write intermediate steps and answers.
15 min	You Do (Individual with Pair-Check)	Students independently solve 2 problems involving addition of fractions/mixed numbers from a line plot, then pair-check answers, discussing strategies.
10 min	Differentiation	Intervention: Use physical fraction pieces. Small group works with more visual and guided practice. Advanced groups solve mixed number problems with denominators up to 50 and 100.
5 min	Closure	Students verbally explain one strategy they used today to add fractions from line plots. Exit ticket: Add 1/6 + 1/3 and write the answer simplified.

Extension Activities

• Create your own line plot by measuring objects at home and recording fractional measures.
• Research a real-world scenario using line plot data (e.g., sports statistics) and prepare a report with fraction computations.
• Use a digital tool to create interactive line plots with fraction data.
